BACKGROUND

The present invention relates generally to mobile computing devices, and more particularly to display of graphical representations of legends in virtualized data formats of mobile computing devices. Charts are graphical representation of data, which may be represented by symbols, such as, bars in a bar chart, lines in a line chart, or slices in a pie chart. Charts are often used to ease understanding of large quantities of data, and the relationships between parts of the data. For example, when data appearing in a chart contains multiple variables, the chart may include a legend. A legend contains a list of the variables appearing in the chart and an example of their appearance. This information thus allows the data from each variable to be identified and displayed in the chart.

DETAILED DESCRIPTION

Detailed embodiments of the claimed structures and methods are disclosed herein; however, it may be understood that the disclosed embodiments are merely illustrative of the claimed structures and methods that may be embodied in various forms. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of this invention to those skilled in the art. In the description, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments.

Graphical chart representations of data may include a main chart display section and a legends display section, for providing details of the data. The main chart section may include docked display of the data, in a form of a chart, such as, a single docked “Pie Chart”, or a “Column” of information, of the data, of the main chart display section. However, the legends display section is typically not docked to a chart area of the main chart display section, but is generally displayed in a separate section of the graphical chart representations. The legends display section may provide capabilities for distinguishing between numerous data points of the data. One of the capabilities of the legends display section may include a display of swatches in the legends display section, for providing additional distinguishing features of the data.

However, it may be difficult to display a main chart display section and a legends display section in mobile computing devices, due to lack of display space, or area for displaying data of the graphical chart representations, in the displays of the main chart display section and a legends display section, all within a single instance of display of the mobile computing devices. As such, it may be advantageous, among other things, to provide a system to display main chart display sections and legends display sections, based on configuration of swatches of the legends display sections, for display of the data of the graphical chart representations in the mobile computing devices, whereby the display of the swatches is based on preferences of a user, client, or systems administrator of the mobile computing devices, for displaying the graphical chart representations.

Referring now to FIG. 2, a functional block diagram 200 illustrating program components and algorithms associated with mobile systems application 114A, in accordance with embodiments.

The mobile systems application 114A may be a web browser plug-in system application program that provides an administrative user-interface, for displaying visualization of swatches of legends in a graphical representation of information, based on preferences, of user, client, or systems administrator, of the mobile systems application 114A, whereby, according to at least on embodiment, the display is based on customized configurations of swipe inputs of swatches of the legends, configured by the client in the administrative user-interface. For example, the computing interface also provides mobile system application functions for configuring the swipe inputs, in the administrative interface, as described below. Also, the mobile systems application 114A may access the mobile systems application 114B, running on mobile server 112, for displaying virtualization of swatches of legends of virtualized graphical representations of information of mobile computing device 102. The mobile systems application 114A may be centralized on the mobile server 112, and also it may be divided between two different components: server-side and client-side.

The mobile systems application 114B, running on mobile server 112 may interact with the web browser of mobile systems application 114A, for transmission of the user configurations for displaying the graphical representation of data in the mobile computing device 102. For example, the mobile systems application 114A may implement a mobile virtualized computing platform for displaying graphical representation of swatches of legends, based on client preferences in a data visualization engine of the mobile systems application 114A.

Also, the mobile application environment 114A may include a hardware virtualization system that enables multiple operating systems, or virtual machines to run or operate simultaneously, and display a virtual, graphical representation of the swatches of legends in the user-interface of the mobile systems application 114A.

For example, in the illustrated environment, the mobile systems application 114A includes virtual machine (VM) 210, mobile hypervisor 260 and virtualized hardware resources 270. The VM 210 provides a virtualized system application platform for supporting the display of the graphical representation of swatches in the user-interface. The VM 210 also executes programs, or applications in mobile operating system (OS) 220, for displaying the graphical representation of swatches, based on configured the client preferences in the mobile systems application 114A.

For example, The VM 210 utilizes data or information of an external source, or of the user, and generates the chart as the output in the mobile OS 220. Also, the VM 210 may also execute program instructions for displaying the information, or data, in a virtualized data format, for display in the mobile computing device 102. For example, the mobile OS 220 may be Android® (Android and all Android-based trademarks and logos are trademarks or registered trademarks of Google, Inc. and/or its affiliates) or Blackberry® OS (Blackberry and all Blackberry-based trademarks and logos are trademarks or registered trademarks of Blackberry, Inc. and/or its affiliates).

The virtualized hardware resources 270 may include, for example, virtual processors, virtual disks, virtual memory or virtual network interfaces that are allocated to VM 210 for executing program operations of mobile OS 220. Also, the mobile hypervisor virtualizes virtualized hardware resources 270, and controls processor scheduling and memory partitions for executing program operations of mobile OS 220, for displaying the graphical representations of charts, based on the user's configured preferences. The mobile OS 220 includes control network interfaces 230, which operates to display the graphical representation of swatches of legends in a data virtualization engine of the VM 210, based on the user, or client preferences.

The control network interface 230 may be a mobile web browser application, a standalone mobile web page graphics display application or part of a service that monitors and interacts with a mobile web browser or graphical display application of VM 210. The control network interface 230 may, among other things, retrieve and display mobile content of mobile communications environment 100 (FIG. 1) via communications network 110 (FIG. 1).

The control network interface 230 includes a charting application 240. The charting application 240 is a computer program that is used to create a graphical representation of information, in a chart display interface of mobile operating system 220, based on non-graphical data or information. For example, the charting application 240 can retrieve information, or data either from the user or from some external source, and create a chart based on the data in the mobile OS 220. The charting application 250 includes, graphical legends configuration application 250, which enables the user, or the systems administrator of mobile OS 220 to configure the display of the legends, in the graphical legends configuration application 250 of the charting application 230, based on preferences of a user, or systems administrator for displaying the graphical representations of the legends in mobile computing device 102, according to embodiments. For example, mobile systems application 114A may receive an input to configure a plurality of swatches of the legends of graphical charts, whereby, the input may include at least one of a threshold number of swatches, identification of graphical area for displaying the swatches, and size or data of the swatches for display in the graphical charts of the data virtualization engine, according to embodiments.

Referring now to FIG. 3, an operational flowchart 300 illustrating steps carried out by a program for displaying for displaying graphical representations of legends in the virtual machine 210 (FIG. 2) of mobile computing device 102 (FIG. 1), based on preferences of a user, or systems administrator for displaying the graphical representations of the legends in the mobile computing device 102 (FIG. 1), according to embodiments.

At 310, mobile systems application 114A (FIG. 1) input to configure a plurality of swatches of the legends of graphical charts, the input includes at least one of a threshold number of swatches, identification of graphical area for displaying the swatches, and size or data of the swatches for display in the graphical charts of the data virtualization engine, whereby, the plurality of swatches is configured in the graphical legends configuration application 250 (FIG. 2) of the charting application 240 (FIG. 2), for display of the legends, based on the received input. Also, display of the swatches in the graphical charts is controlled by pivots of the data virtualization engine, in the VM 210 (FIG. 2), based on the user preferences. For example, the pivot provides a centralized location of the VM 210, for controlling display of the swatches in the graphical charts. Also, the swatches may be scrollable in an area of the display of the graphical charts, based on the received input of size, or data for displaying the swatches, from the user, or systems administrator. Further, at 320, the mobile systems application 114A modifies the legend swatches, based on the received input. In addition, at 330, the mobile systems application 114A generates a plurality of graphical charts of the virtual machine, for displaying the swatches of the legends, according to embodiments.

Referring now to FIG. 4, an operational flowchart 400 illustrating steps carried out by a program for displaying graphical representations of data, or information in the mobile computing device 102 (FIG. 1), according to embodiments. At 410, mobile systems application 114A (FIG. 1) displays a graphical chart representation of data, and accompanying legends display of the represented data in the virtual machine 210 (FIG. 2) of mobile operating systems 220 (FIG. 2). For example, at first, the user starts a Mobile App, such as, mobile systems application 114A (FIG. 1), to work with charts and visualizations of data, or information that the user desires to work with or see. As such, the user can then load the desired chart in the application, such as, charting application 240 (FIG. 2), to see or configure the display of the chart. In such a case, the chart will have main visualization and legend sections displayed, in the charting application 240 (FIG. 2), based on the user's preferential configuration for displaying the main chart visualization section or legend section, for displaying the charts in mobile computing device 102 (FIG. 1), according to embodiments.

Next, at 420, it is determined, by mobile systems application 114A (FIG. 2), whether a request to display the graphical chart representation, by the user, or the systems administrator of mobile operating systems 220 (FIG. 2), is received with a notification of swipe input for configuring display of the legends of the mobile systems application 114A (FIG. 2), whereby, for instance, the swipe inputs are configured by the user, or the systems administrator in graphical legends configuration application 250. For example, mobile systems application 114A (FIG. 2), may wait for a user actions for configuring display of the legends section of the chart in charting application 240 (FIG. 2), primarily based user's decision, of whether user desires to see more data of the chart. As such, the user may swipe left, or right, of the charting application 240 (FIG. 2), to configure display on the legends sections of the chart.

If it is determined at 420 that the request to display the graphical chart representation is received with the notification of swipe input for configuring display of legends of the graphical chart in the mobile systems application 114A (FIG. 2), then at 430, graphical legends configuration application reconfigures, recreates, or redraws the display of the graphical chart and display data of the graphical charts in a form of swatches of the legends, in the mobile operation system 220 (FIG. 2), for viewing by the user, or the systems administrator of the mobile computing device 102 (FIG. 1).

However, if it is determined at 420 that the request to display the graphical chart representation is not received with the notification of swipe input for configuring display of legends of the graphical chart in the mobile systems application 114A (FIG. 2), then at 410, mobile systems application 114A (FIG. 1) subsequently displays a graphical chart representation of data, and accompanying legends display of the represented data in the virtual machine 210 (FIG. 2) of mobile operating systems 220 (FIG. 2).

Referring now to FIG. 5, an operational flowchart 500 illustrating steps carried out by a program for configuring, in graphical legends configuration application 250 (FIG. 2) of the charting application 230 (FIG. 2), display of graphical representations of legends in the mobile computing device 102 (FIG. 1), based on preferences of a user, or systems administrator for displaying the graphical representations of the legends in mobile computing device 102 (FIG. 1), according to embodiments.

At 510, graphical legends configuration application 250 (FIG. 2) of the charting application 230 (FIG. 2), is displayed to a user of mobile computing device 102 (FIG. 1), for configuring display of legends of graphical representations of data, or information in the mobile computing device 102 (FIG. 1). At 520, graphical legends configuration application 250 (FIG. 2) receives user configuration inputs of a threshold number of swatches of the legends of the graphical chart representation, that the user prefers to be displayed in mobile computing devices 102 (FIG. 1), whereby, the receives input is based on the user's configuration preferences for displaying the graphical legends.

Next at 530, it is determined, by the graphical legends configuration application 250 (FIG. 2), whether the user prefers display of reduced number of swatches of the legends of graphical representations of data, or information, in the mobile computing device 102 (FIG. 1), according to embodiments. If it is determined, by the graphical legends configuration application 250 (FIG. 2), that he user prefers display of reduced number of swatches of the legends of graphical representations of data, or information, in the mobile computing device 102 (FIG. 1), then, at 540, the graphical legends configuration application 250 (FIG. 2) stores the user's preferred configured display of number of swatches of the legends of graphical representations of data, or information, in the mobile computing device 102 (FIG. 1). However, if it is determined by the graphical legends configuration application 250 (FIG. 2) that the user does not prefer display of a reduced number of swatches of the legends of graphical representations of data, or information, in the mobile computing device 102 (FIG. 1), the method ends.

Referring now to FIG. 6, an operational flowchart 600 illustrating steps carried out by a program for configuring, in graphical legends configuration application 250 (FIG. 2) of the charting application 230 (FIG. 2), configuration of display of multiple swipe actions of the graphical representations of legends in the mobile computing device 102 (FIG. 1), based on preferences of a user, or systems administrator for displaying the graphical representations of the legends in mobile computing device 102 (FIG. 1), according to embodiments.

At 610, the user of mobile computing device 102 (FIG. 1), performs multiple swipe action on legends swatch displays, in the graphical legends configuration application 250 (FIG. 2), of the graphical representations of legends. At 620, it is determined whether a final or last swatch of the legends display is reached. As such, if it is determined that the last swatch of legends display is reached, then at 630, the graphical legends configuration application 250 (FIG. 2), reloads a first swatch of the legends swatches in the display of the graphical legends configuration application 250 (FIG. 2), according to at least one implementation of the present embodiment. However, if it is determined, that the last swatch of the legends has not been reached, then, at 610, graphical legends configuration application 250 (FIG. 2), receives input, from the user, of multiple swipe action on legends swatch displays, in the graphical legends configuration application 250 (FIG. 2), of the graphical representations of legends.
